""" Task: Exercise 6.6
    Read the documentation of the string methods at
    docs.python.org/lib/string-methods.html. You might want to experiment with
    some of them to make sure you understand how they work. strip and replace
    are particularly useful. The documentation uses a syntax that might be
    confusing. For example, in find(sub[, start[, end]]), the brackets indicate
    optional arguments. So sub is required, but start is optional, and if you
    include start, then end is optional.
